CORBIN  HARDWARE 


THE  TERM  “Corbin  Hardware”  covers  the 
most  comprehensive  and  best  assorted  line  of 
locks  and  finishing  hardware  made.  Every  article 
has  been  subjected  to  rigid  tests,  both  as  to  its 
quality  and  finish  and  its  desirability  from  the  cus¬ 
tomers’  view  point,  and  in  consequence  the  name 
of  Corbin  carries  with  it  a  sense  of  superiority  and 
desirability.  The  name  is  a  guarantee  of  excellence. 

From  time  to  time,  Corbin  inventors  have  de¬ 
veloped  specialties  which  have  shown  so  great  an 
improvement  over  anything  then  in  existence  as  to 
warrant  special  mention  and  a  special  regard  in  the 
esteem  of  those  who  erect  and  equip  buildings  of 
the  finest  types.  This  book  is  devoted  to  some  of  the 
newest  and  most  important  of  these  specialties  and 
you  will  find  its  pages  well  worth  a  careful  reading.

THE  CORBIN  CONCEALED  TRANSOM  LIFTER 


Fig.  2 

TYPICAL  CORRIDOR  OR  ROOM  DOOR  IN  A  MODERN  OFFICE 
OR  HOTEL  BUILDING.  BOTTOM-HINGED  TRANSOMS  ARE  GEN¬

OF  AIR  UPWARD  AND  AWAY  FROM  THE  OCCUPANTS  OF  THE  ROOM. 

No.  075  FOR  BOTTOM  -  HINGED  TRANSOMS 

For  instructions  for  ordering,  see  page  15. 

Characteristics  of  the  Corbin  Concealed  Lifter 

The  only  portion  visible  is  the  bronze  metal  T  handle  and 
plate,  which  can  be  finished  to  correspond  with  the  other  hard¬ 
ware. 

It  is  noiseless  in  operation,  never  wears  out  or  gets  out  of  order, 
requires  no  adjustment  after  being  installed  and  costs  nothing 
for  upkeep  or  repairs. 

It  is  equally  applicable  to  steel  or  wood  trim,  and  can  be  used 
in  partitions  as  thin  as  two  inches. 

It  will  operate  any  style  or  size  of  transom,  whether  bottom, 
center  or  top  hung,  right  or  left  hand,  swinging  in  or  out.  It  is 
therefore  adapted  to  suit  the  swing  of  the  door,  or  other  conditions 
of  use  or  construction.

of  mechanism, 
see  page  10. 


Turning  the  T  handle  operates  any  of  the  Corbin  concealed 
transom  lifters.  The  handle  turns  easily,  only  one  hand  being 
required  to  open  or  close  a  transom.  The  leverage  gives  a 
powerful  and  positive  action,  and  the  mechanism  is  so  arranged 
that  the  transom  is  firmly  held  in  any  position,  obviating  the  use 
of  catches  or  other  locking  devices.

An  oiling  tube  is  provided,  so  that  the  mechanism  in  the  gear 
case  may  be  lubricated  with  an  ordinary  oiler  without  removing 
or  disturbing  any  of  the  parts. 

Mechanically  Correct 

Every  care  has  been  taken,  both  in  design  and  construction, 
to  give  the  maximum  of  efficiency.  The  mounting  of  all  parts  on  a 
single  back  plate  ensures  the  proper  operation  and  freedom  from 
For  description  binding.  Special  dies  have  been  employed,  so  that  all  parts  are 

of  mechanism,  interchangeable.  Provision  is  made  against  looseness  of  parts

AND  A  DIFFERENT  SASH  PLATE  IS 
USED. 


Since  all  the  mechanism  is  attached  to  a  single  back  plate  and 
as  a  unit,  the  Corbin  Concealed  Transom  lifter  is  both  easy  to 
install  and  certain  to  operate  satisfactorily.  The  usual  blocking 
is  not  interfered  with.  The  lifter  should  be  applied  on  the  side 
of  the  door  next  to  the  lock  so  as  not  to  interfere  with  the  buck  and 
jamb  on  the  hinge  side.  Figures  13  and  14  illustrate  the  best  form 
of  the  buck,  but  if  not  so  made,  it  can  be  easily  cut  so  as  to  per¬ 
mit  the  insertion  of  the  gear  case  and  pivot  levers. 

Instructions  for  applying  are  packed  with  each  lifter.  (Continued)

(Continued)  Its  Economic  Value 

The  value  of  a  transom  for  ventilation  depends  absolutely 
upon  the  device  that  operates  it.  If  the  transom  is  hard  to 
open  or  if  the  lifter  is  broken  or  out  of  order  no  attempt  is  made 
to  secure  ventilation  through  this  means  and  the  transom  is  use¬ 
less.  Therefore,  it  is  most  important  that  the  transom  lifter  be 
easily  operated,  thoroughly  reliable  and,  because  of  the  number 
employed,  that  it  should  require  no  attention  and  should  last 
as  long  as  the  building  does.  The  Corbin  concealed  transom 
lifter  has  all  the  desired  characteristics  and.  further,  it  possesses 
them  in  a  degree  to  be  found  in  no  other  device  for  governing 
transoms,  and  has  some  features  which  are  not  found  elsewhere. 
The  transoms  of  a  large  building,  properly  equipped,  will 
give  better  ventilation  than  any  system  of  forced  draught  for 
the  halls  and  corridors  from  natural  flues  through  which  the  warm 
air  of  the  rooms  seeks  to  escape,  causing  a  strong  current  whenever 
an  opening  is  found  through  which  the  air  can  pass.  The  health 
and  comfort  of  tenants,  and  the  desirability  of  rooms  is  materially 
affected  by  the  quality  of  the  air  and  possibility  of  arranging 
for  free  currents  when  desired  and  perfectly  controlling  them. 
Hence  the  necessity  for  such  a  device  as  the  Corbin  Concealed 
Transom  lifter,  especially  designed  forservice  under  all  conditions.

A  No.  074  transom  lifter  attached  to  three  parallel  transoms  in  corridor  of  an  office  building.  The  easy 
and  positive  action  makes  it  possible  to  operate  any  number  of  transoms  hung  in  this  way  as  easily  as  one.

move  as  one  and  are  as  easily 
and  positively  governed  as  a 
single  sash. 

Any  number  of  transoms 
placed  perpendicularly  to  one 
another  can  be  operated  with 
the  Corbin  Concealed  Transom 
Lifter.

This  shows  the  T  handle  and 
the  front  of  gear  case  broken 
away  to  expose  the  mechanism. 

The  T  handle  and  plate  are 
the  only  visible  portions,  the 
balance  being  mounted  within 
the  casing. 

The  toothed  segment  attached 
to  the  worm  spindle  gear  per¬ 
mits  an  adjustment  that  will 
place  the  handle  in  the  center 
of  the  casing. 

The  worm  gear  multiplies 
the  leverage  and  enables  the 
transom  to  be  moved  with 
little  pressure  on  the  handle, 
and  also  holds  the  transom 
firmly  fixed  at  any  angle. 

The  rack  moves  up  and  down 
as  the  handle  is  turned,  actuat¬ 
ing  the  transom. 

Fig.  9 


This  shows  the  back  of  the  gear  case, 
with  the  assembly  plate  removed. 

The  ball-tip  oiler  protrudes  through 
the  jamb.  Pressing  the  spout  of  an  or¬ 
dinary  oiler  against  the  ball  causes  it  to 
recede,  opening  the  tube  for  admission 
of  lubricant. 

The  two  bolts  pass  through  the  jamb 
and  attach  the  lifter  firmly  to  it.  These 
bolts  are  located  outside  of  the  door  stop 
on  the  jamb. 

The  rack  and  gear  are  shown  where 
cover  is  broken  away.  The  rack  is 
moved  up  and  down  as  the  gears  are 
rotated  by  the  turning  of  the  handle.

Figure  11  illustrates  the  upper  end  of  the  lifter  and 
shows  the  compound  lever,  which  gives  a  powerful  action 
in  a  small  space.  The  arrangement  of  the  parts  is 
different  in  No.  073  from  that  in  Nos.  074  and  075,  in 
order  to  reverse  the  movement,  but  the  same  parts  and 
the  same  effect  obtains  in  all. 


The  sash  plate,  with  the  noiseless  slide,  raises  and 
lowers  the  transom  without  jar  or  noise. 


Fig.  11 


Figure  12  illustrates  the  hinged  lower  end  of  the  con¬ 
necting  rod,  and  shows  the  means  by  which  a  direct  pull 
upon  the  compound  lever  is  obtained  without  affecting 
the  action  of  the  rack  and  gear.  This  provision  ab¬ 
solutely  prevents  any  possibility  of  sticking  or  binding. 
The  spring  absorbs  any  back-lash.

THE  CORBIN  CONCEALED  TRANSOM  LIFTER 


Figure  13  shows  a  horizontal  section  of  a  typical  wood  jamb,  at  the  gear  case,  which  is  usually  located 
about  four  feet  from  the  floor  line.  It  is  necessary  to  set  the  buck  back  from  the  jamb  ^  inch.  This  does 
not  interfere  with  the  usual  blocking  between  the  buck  and  the  jamb.  A  notch  3f  inches  in  height  by 
lfxlF  inches  horizontal  must  be  cut  in  the  buck,  which  will  give  ample  space  for  the  insertion  of  the  lifter. 

The  T  handle  is  located  on  a  flat  surface  of  the  casing.  The  construction  of  the  gear  case,  as  shown 
in  figure  9,  permits  a  wide  range  of  adjustment  to  fit  different  widths  of  casing.  The  screws  for  attaching  the 
lifter  to  the  jamb  are  shown  in  figure  10. 


1 figure  14  shows  a  horizontal  section  of  the  same  trim  shown  in  figure  13,  but  taken  at  the  pivot  point 
of  the  transom  sash.  1  he  buck  must  be  set  |  inch  from  back  of  jamb  on  the  lock  side  of  the  door,  as  ex¬ 
plained  above.  The  construction  on  the  hinged  side  of  the  door  is  not  affected.  The  sash  may  be  pivoted 
at  bottom,  center  or  top  and  open  to  any  point  up  to  45  degrees. 

Complete  details  will  be  furnished  for  installation.

Figure  15  represents  a  two  inch  plaster  wall  with  a  split  jamb.  The  section  is  shown  at  the  gear  case, 
located  approximately  four  feet  from  the  floor  on  the  lock  side  of  the  door.  The  jamb  is  3T3g  inches  in  width. 
Any  width  less  than  this  makes  the  use  of  a  concealed  transom  lifter  impossible  on  this  particular  construction 
The  gear  case  and  all  other  parts  are  standard.

shows  the  pivot  bearing  and  a  ljj  inch 
transom,  which  may  be  hinged  at  top, 
center  or  bottom  as  may  be  desired. 

The  two  inch  wall  is  the  latest  de¬ 
velopment  in  modern  design  of  buildings, 
and  the  Corbin  concealed  transom  lifter 
is  the  only  device  which  can  be  used  on 
the  limited  space  which  the  narrow  con¬ 
struction  affords.

THE  CORBIN  AUTOMATIC  EXIT  FIXTURES 


FOR  SINGLE  AND  DOUBLE  DOORS,  OPENING  OUT 


Fig.  22 


Fig.  21.  Top  Strike 

These  fixtures  provide  a  ready  exit  at  all  times,  as  the  doors 
to  which  they  are  applied  can  always  be  opened  from  the  inside, 
even  when  locked  against  entrance.  They  yield  to  a  light 
pressure,  so  that  a  child  can  operate  them  with  ease. 

Originally  designed  as  a  preventive  of  loss  of  life  through

The  Corbin  Concealed  Casement  Operator 

For  Windows  Opening  Outward 


A  DEVICE  FOR  OPENING  AND  CLOSING  CASEMENT  WINDOWS  EASILY  AND  QUIETLY 
AND  HOLDING  THEM  FIRMLY  FASTENED  AT  ANY  POINT  I  ROM  A  CLOSED  TO  A  WIDE-OPEN  POSITION.

P.  &  F.  CORBIN 

THE  AMERICAN  HARDWARE  CORPORATION  ,  Successor 

New  Britain,  Conn.,  U.  S.  A. 

NEW  YORK  CHICAGO  PHILADELPHIA 


THE  CORBIN  CONCEALED  CASEMENT  OPERATOR 


The  No.  60  Casement  Operator 

This  device  permits  the  opening  and  closing  of  casement  windows 
without  interference  with  curtains  or  window  screens.  It  locks  the 
sash  securely  at  any  point  from  closed  to  wide  open,  making  catches 
or  sash  locks  unnecessary.  It  presents  no  protruding  bars  or  braces; 
employs  no  thumb  screws,  requires  no  effort  to  operate,  and  never 
gets  out  of  order.  It  is  the  solution  of  the  problem  of  how  to  satis¬ 
factorily  handle  casement  windows  where  comfort,  quietness,  and 
ease  of  manipulation  are  desired. 

Figure  1  shows  the  operator  with  all  parts  in  position  as  in  use. 
The  actuating  mechanism  is  simple,  consisting  of  a  worm  and  gear, 
greatly  multiplying  the  leverage  and  enabling  a  child  to  open  or  close 
any  window  with  ease.  Windows  which  stick  from  paint  are  easily 
forced  loose.  The  most  severe  wind  storms  neither  move  the  sash 
or  make  it  difficult  to  move.  The  window  is  governed  easily  under 
all  conditions  by  the  use  of  the  handle  and  cannot  be  moved  except 
by  the  handle,  being  securely  locked  in  any  position  in  which  it  may 
be  placed. 


Figure  2.  The  No.  60  Casement  Operator  Applied. 


THE  CORBIN  CONCEALED  CASEMENT  OPERATOR 


The  gear  ease  is  made  to  retain  lubricant.  A  screw  hole  plainly  marked  “oil”  permits  lubrication.  Vase¬ 
line,  with  a  small  quantity  of  flake  graphite,  well  mixed,  is  the  best  lubricant,  although  oil  or  heavy  grease  can 
be  satisfactorily  substituted. 

The  exterior  parts  are  galvanized.  The  gear  is  accurately  machined  from  a  high  grade  bronze  casting,  and 
the  worm  is  made  from  steel,  ensuring  good  wearing  qualities  and  ease  of  operation,  and  making  it  impossible 
for  the  two  parts  to  be  fastened  together  by  corrosion. 


The  sash  plate  is  also  shown 
attached  to  the  bottom  of  the 
casement,  broken  away  to  show 
the  bronze  slide  on  the  end  of  the 
pivot  crank,  which  slides  easily 
in  a  finished  slot  in  the  plate  as 
the  handle  is  turned  and  the 
window  is  opened  or  closed. 

It  is  not  necessary  to  place  the 
casement  operator  so  that  the 
pivotal  center  coincides  with  the 
hinge  center  of  the  casement, 
the  slide  in  the  sash  plate  per¬ 
mitting  the  sash  to  swing  freely 
without  binding.

hold  the  gear  case  in  position  are 
also  shown.  These  pass  upward

from  the  weather. 


ment  windows  fitted  with  two 
Corbin  Concealed  Casement  Op¬ 
erators.  When  the  windows  are 
closed  the  only  parts  that  are 
visible  are  the  crank  handles  and 
escutcheons  which  are  unobtru¬ 
sive  and  out  of  the  way.

The  handles  and  plates  can  be  finished  to  match  the  other  hardware  used.  When  the  projection  of  the 
stool  interferes  with  the  use  of  a  crank,  a  tee  handle  is  provided.  If  so  ordered,  the  handles  can  be  made  de¬ 
tachable,  so  that  only  the  roses  are  seen — a  valuable  feature  when  it  is  desired  to  have  one  person  control  the 
opening  and  closing  of  the  window.

Figure  4.  Details  of  Application. 

When  ordering,  the  dimensions  at  A,  B  and  C 
should  be  given. 


The  No.  60  Casement  Operator  is  not  difficult  to 
apply.  It  should  be  put  in  place  before  the  apron 
and  stool  are  attached  and  a  few  simple  rules  for 
properly  installing  it  should  be  carefully  observed. 
It  can  be  used  with  any  detail  of  sash  and  sill  and 
will  give  perfect  service  without  adjustment  after 
being  properly  applied. 

The  gear  case  must  be  set  with  the  top  plate 
level.  If  the  bottom  of  the  sill  is  not  level,  a  wedge 
of  the  proper  size  should  be  inserted  between  the 
sill  and  the  top  of  the  gear  ease  as  shown  in  Figure  4. 

The  position  of  the  gear  case  can  be  varied  to 
suit  the  construction  of  the  sash  and  sill,  but  its 
center  should  never  be  more  than  inches  at  D 
of  4j>4  inches  at  E  as  indicated  in  Figure  4.  These 
figures  mark  the  extreme  limit  at  which  the  arm  will 
make  proper  connection  with  the  sash  plate  to  get 
the  desired  free  action.  Ordinarily,  the  center  of 
the  gear  case  is  placed  2  inches  from  the  jamb,  and 
1^2  inches  from  the  stop,  and  these  figures  should  be 
used  when  possible. 

When  the  stool  extends  over  the  top  of  the  gear 
case,  the  under  side  of  the  stool  should  be  cut  away, 
as  shown  in  Fgure  4,  in  order  that  the  arm  may  move 
freely. 

Full  instructions  for  application  are  packed  with 
each  Casement  Operator. 


The  Corbin  No.  60  Concealed  Operator  is  the 
most  reliable  device  made  for  controlling  the  action 
of  casement  windows.  There  are  no  parts  that 
rattle;  none  that  have  to  withstand  undue  strain 
and  wear;  none  that  are  affected  by  use  or  weather. 
The  worm  and  gear  so  reduce  the  effort  required  to 
open  and  close  the  window  that  a  child  can  operate 
it  with  ease.

THE  CORBIN  CONCEALED  CASEMENT  OPERATOR 


FOR  WINDOWS  OPENING  OUTWARD 


NO.  60  CONCEALED  CASEMENT  OPERATOR  IN  USE 

This  device  permits  the  opening  and  closing  of  casement  windows  without  interference  with  curtains 
or  window  screens.  It  locks  the  sash  securely  at  any  point  from  closed  to  wide  open,  making  catches  or  sash 
locks  unnecessary.  It  presents  no  protruding  bars  or  braces;  employs  no  thumb  screws,  requires  no  effort 
to  operate  and  never  gets  out  of  order.  It  is  the  solution  of  the  problem  of  how  to  satisfactorily  handle 
casement  windows  in  fine  residences,  where  comfort,  quietness  and  ease  of  manipulation  are  desired. 

Figure  58  shows  the  casement  operator  applied,  the  window  'stool  [and  apron  being  broken  away  to 
show  the  gear  case,  pivot  bearing  and  pivot  crank. 

The  bolts  which  hold  the  gear  case  in  position  are  also  shown.  These  pass  upward  through  the  wood 
sill  and  hold  the  case  securely  in  position  under  the  window  sill  where  it  is  entirely  enclosed  and  pro¬ 
tected  from  the"weather. 

l'he  gear  case  is  constructed  so  as  to  retain  lubricant.  Provision  is  made  for  lubrication  when  desired. 

The  illustration  also  shows  the  sash  plate  attached  to  the  bottom  of  the  casement  sash,  broken  away  to 
show  the  bronze  roller  on  the  end  of  the  pivot  crank,  which  slides  easily  in  a  finished  slot  in  the  plate  as  the 
handle  is  turned  and  the  sash  is  opened  or  closed.

A  PAIR  OF  CASEMENT  WINDOWS  EQUIPPED  WITH 
No.  60  CORBIN  CONCEALED  CASEMENT  OPERATOR 

The  casement  operator  can  be  used  upon  either  right  or  left  hand  windows  by  a  simple  reversal  of  parts, 
which  can  be  easily  made  when  the  device  is  applied.  It  can  be  supplied  for  casements  opening  inward 
when  desired. 

The  actuating  mechanism  employed  consists  of  a  worm  and  gear  greatly  multiplying  the  leverage  and 
enabling  a  child  to  open  or  close  any  window  with  ease.  Windows  which  stick  from  paint  are  easily  forced 
loose.  The  most  severe  wind  storms  neither  move  the  sash  nor  make  it  difficult  to  move  them.  The  window 
is  governed  easily  under  all  conditions  by  the  use  of  the  handle  and  cannot  be  moved  except  by  the  handle, 
being  securely  locked  in  any  position  in  which  it  may  be  placed. 

Figure  59  shows  a  pair  of  casement  windows  fitted  with  two  Corbin  concealed  casement  operators. 
It  will  be  seen  that  the  only  parts  visible  are  the  crank  handles  and  plates,  whether  the  windows  are  opened 
or  closed;  these  can  be  finished  to  match  the  other  hardware  used.  If  desired  the  handles  can  be  made 
detachable  so  that  only  the  roses  are  seen.

Figure  60  is  a  vertical  section  through  the  window  sill  and  stooling,  showing  the  gear  case,  the  worm 
gear,  the  vertical  connection  to  the  pivot  arm  and  the  sash  plate  attached  to  the  bottom  of  the  window. 
The  spindle  may  be  of  any  length  to  suit  the  conditions  of  use. 

The  thickness  of  the  sill  may  measure  from  If  to  4  inches  in  length,  varying  by  f  inch. 

The  casement  sash  shown  in  Figure  60  is  If  in.,  the  size  most  generally  employed.  Plates  can  be  sup¬ 
plied  for  other  thicknesses,  from  If  to  2\  inches. 

A  screw-hole,  plainly  marked  “oil’’  permits  lubrication.  Vaseline,  with  a  small  cpiantity  of  flake  graphite 
well  mixed,  is  the  best  lubricant,  although  oil  or  heavy  grease  can  be  satisfactorily  substituted. 

1  he  exterior  parts  are  galvanized.  The  gear  is  accurately  machined,  from  high  grade  bronze  castings, 
and  the  worm  is  made  from  steel,  ensuring  maximum  wear  and  smoothness  of  operation,  and  making  it 
impossible  for  the  two  parts  to  be  fastened  together  by  corrosion.

The  Corbin  Concealed  Casement  Operator  will  not  break  after  being  installed,  but  parts  may  be  broken 
or  lost  before  being  attached.  The  above  list  is  supplied  to  facilitate  replacement  if  such  contingencies 
arise. 

INSTRUCTIONS  FOR  ORDERING 

Furnish  full  size  detail  showing  section  through  sill,  same  as  figure  60.  The  thickness  of  the  sill  must  be 
given. 

The  casement  operator  can  be  used  on  either  right  or  left  hand  windows  as  desired.  Means  are  also  pro¬ 
vided  for  placing  the  rose  and  handle  in  the  center  of  the  apron. 

It  is  not  necessary  to  place  the  casement  operator  so  that  the  pivotal  center  coincides  with  the  hinge 
center  of  the  casement,  the  moving  roller  in  the  sash  plate  permitting  the  sash  to  swing  freely  without  binding.

37 


THE  CORBIN  CONCEALED  SHUTTER  WORKER 


This  device  permits  the  blinds  to  be  opened  or  closed  without  opening  the  window  or  screen.  The  handle 
and  rose  on  the  apron  of  the  window  are  the  only  visible  parts.  It  is  made  in  two  forms  as  described  below. 

In  No.  063  a  worm  and  gear  mechanism  is  employed.  This  makes  the  shutter  worker  very  easy  to 
operate  and  also  serves  to  lock  the  shutter  firmly  at  any  point,  so  that  it  is  not  affected  by  the  action  of  the 
wind  and  making  it  unnecessary  to  use  any  other  fastening  to  hold  the  shutter  in  either  the  closed  or  wide 
open  position. 

The  mechanism  is  finely  and  accurately  made,  ensuring  perfect  action.  All  exposed  parts  are  heavily 
galvanized. 

In  No.  064  a  spiral  gear  and  pinion  are  provided  which  give  the  same  easy  action  and  hold  the  shutter 
fast  in  either  a  closed  or  wide  open  position  only.  It  will  remain  stationary  in  other  positions  under  ordinary 
conditions  and  if  a  gust  of  wind  closes  it  or  throws  it  wide  open  it  is  firmly  locked  and  banging  is  made 
impossible.  This  is  accomplished  by  a  locking  device  in  the  rose.  When  desired  the  rose  can  be  supplied 
with  intermediate  locking  points  but  unless  otherwise  specified  will  lock  only  in  the  wide  open  or  closed 
positions.

If  it  is  desired  to  use  a  folding  blind  hinged  in  the  center,  we  can  supply  a  fixture 
to  meet  the  different  conditions  which  will  ensure  the  automatic  action  of  the  tree 
section,  bringing  it  to  its  proper  place,  fully  extended  when  the  blind  is  closed  and 
holding  it  folded  close  to  the  hinged  section  when  the  blind  is  opened.

The  foregoing  list  of  parts  is  furnished  as  a  guide  to  ordering  if  any  portion  is  lost  or  damaged  in  handling 
previous  to  being  applied  to  the  window.  After  it  is  in  use  there  will  be  no  breakage  or  need  of  new  parts. 

INSTRUCTIONS  FOR  ORDERING 

Furnish  a  full-sized  section  as  shown  in  figure  64.  There  must  be  at  least  If  inches  from  the  storm  sill 
to  the  top  of  the  wood  sill  or  the  bottom  of  the  blind.  Gear  cases  BW1  and  BW2  have  flanges  1£  inches  in 
height  where  they  screw  to  the  sill.  The  crank  handle  spindle  comes  in  the  center  of  the  flange  and  the  full- 
sized  section  of  sill  serves  to  locate  the  crank  spindle  and  rose.

I  he  out  fit  consists  of  a  hook  pull,^  mortise  latch,  with  rose  and  push  button  and  an  adjustable  stay. 
It  is  used  in  connection  with  shutters  especially  constructed  for  blind  awnings,  the  lower  section  of  slats  being 
fitted  to  a  separate  frame  hinged  at  the  top. 

lo  open,  pressure  on  the  push  button  withdraws  the  latch  bolt,  when  a  gentle  push  on  the  blind  tilts 
the  movable  section  to  the  desired  angle.  The  friction  of  the  slide  in  the  stay  is  so  adjusted  that  it  will  hold  the 
awning  section  in  any  position  against  any  wind  pressure. 

To  close,  simple  insert  a  finger  in  the  hook  pull  and  draw  the  awning  section  to  a  closed  position.

The  No.  0198§-  friction  stay  joint  consists  of  a  U  shaped  channel  which  is  screwed  to  the  jamb.  A 
spring  block  slides  therein  and  is  connected  to  a  steel  arm  which  is  provided  with  a  fastening  for  either 
the  edge  or  face  of  sash  as  desired.  When  used  as  in  Figure  67  it  is  practically  concealed  when  the  sash 
is  closed;  when  attached  to  the  face  it  is  entirely  exposed.

THE  CORBIN  UNIT  LOCK 


Fig.  71 

LOCK  COMPLETE  SHOWING  INTERIOR  MECHANISM 

This  lock  possesses  a  number  of  advantages,  the  value  of  which  is  readily  recognized. 

1.  It  is  made  in  a  unit,  sold  as  a  unit  and  applied  without  detaching  any  parts.  The  architect  and 
owner  can  be  shown  the  lock  just  as  it  will  appear  in  use  and  there  is  no  possibility  of  loss  of  parts  or  of 
disturbing  the  adjustment  made  at  the  factory. 

2.  All  the  moving  parts  are  attached  to  and  contained  within  a  solid  cast  frame.  This  makes  possible 
a  nicety  of  adjustment  and  close  fit  which  eliminate  looseness  and  rattling.  A  play  of  .004  inch  in  the  knob 
gives  a  smooth  positive  action  and  a  rigidity  and  strength  not  obtainable  with  other  locks.  The  swelling 
and  shrinking  of  doors  cannot  affect  the  action. 

3.  The  Corbin  Pin  Tumbler  Cylinder  is  employed  mounted 
in  the  knob,  where  it  can  be  found  with  ease  in  the  dark.  The 
cylinder  has  all  the  features  described  on  page  49  and  its  location 
commends  it  to  the  favor  on  sight.  Its  advantages  need  no  com¬ 
ment. 

4.  The  knobs  have  screwless  spindles  and  never  work  loose. 
They  have  the  easy  smoothness  of  action  of  the  knob  of  a  safe- 
lock.  One-eighth  of  a  turn  operates  the  lock. 

5.  The  form  permits  the  use  of  the  most  improved  mechanism. 
This  includes  broad,  heavy  latch  bolts  of  the  swinging  type, 
impossible  in  thin  lock  cases,  with  a  long  throw,  making  it  cer¬ 
tain  that  the  latch  enters  the  strike,  a  direct  pull  on  the  latch 
bolt  reducing  the  friction  and  giving  a  lively  action  with  a  resili¬ 
ent  spring,  and  the  use  of  a  very  few  parts  of  simple  construction 
making  the  lock  very  strong  and  not  affected  by  wear  or  abuse 
in  use.

THE  CORBIN  UNIT  LOCK 


6.  It  is  easy  to  apply,  the  cut  in  the 
edge  of  the  door  being  made  by  saw  and 
chisel,  only  ten  minutes  being  required  to 
attach  a  lock.  If  desired,  the  doors  can  be 
cut  at  the  mill,  obviating  any  danger  of 
injury  to  finish  when  attaching  the  lock. 

The  heavy  cast  escutcheons  make  the  door 
stronger  at  the  lock  than  at  any  other 

point.  Inside  Knob  and  Locking  Ring 

7.  The  protected  box  strike  prevents  any  possibility  of  burglarious  attack  from  the  face  of  the  lock 


8.  Locks  of  different  functions  cover  all  modern  requirements 
completely  and  fully.  Note  the  list  on  page  47.

9.  The  locks  are  adjustable  to  doors  of  all  thicknesses. 
I  hey  are  reversible  for  right  and  left  hand  except  when 
the  ornamentation  of  the  escutcheon  prevents  reversing. 
They  are  supplied  in  all  designs  of  Corbin  hardware.

Easy  Swinging  Latch  and  Roll  Backs 


10.  I  hey  are  thoroughly  reliable.  Their  value  is  recognized  where  the  highest 
possible  degree  ol  quality  and  security  is  desired.  They  have  been  placed  in  fine 
buildings  for  fourteen  years  and  the  first  locks  produced  are  giving  perfect  service 
to-day.  A  list  of  buildings  of  national  repute  will  be  supplied  on  application.

THE  CORBIN  DOOR  CHECK  AND  SPRING 


Fig.  91 

No.  1911  Model 

The  1911  Model  Door  Check  has  an  unequalled  record  for  reliability.  Of  the  first  one  hundred  thousand 
checks  made,  only  three  proved  unsatisfactory  and  these  had  springs  broken  from  flaws  in  the  material. 
It  is  strong  and  generously  proportioned  and  requires  no  attention.  It  cannot  leak  and  is  not  affected  by 
extremes  of  temperature. 

Hold-back  attachment  is  furnished  when  so  ordered. 

Right  or  left  hand  without  change. 

Special  arms  are  supplied  for  unusual  applications. 

Removable  key  adjustment  supplied  for  insane  asylums  or  other  places  where  there  is  liability  of  tam¬ 
pering. 

Instructions  for  applying  are  packed  with  each  check. 

Six  sizes  cover  all  requirements,  as  follows: 

No.  1.  For  screen  doors. 

No.  2.  For  doors  between  dining-room  and  butler’s  pantry,  car  doors,  etc.,  or  any  inside  door  not  over 
7  feet  by  3  feet. 

No.  3.  For  outside  doors  not  larger  than  7  feet  by  feet,  steamboat  doors,  vestibule  doors,  etc. 

No.  4.  For  outside  doors  not  larger  than  feet  by  3  feet. 

No.  5.  For  doors  not  larger  than  1\  feet  by  4  feet. 

No.  6.  For  extra  high  doors  and  extra  heavy  doors,  such  as  are  used  in  public  buildings,  stores,  hotels, 
railroad  depots,  etc. 

If  the  door  is  unusually  heavy,  or  very  strong  draughts  are  to  be  encountered,  use  one  size  larger  than 
specified  or  write  us  telling  of  conditions  and  receive  instructions. 

The  Corbin  door-check  book,  describing  all  styles  of  overhead  and  floor  checks  made  will  be  sent  upon 
application.

THE  CORBIN  BALL-BEARING  PIN  TUMBLER  CYLINDER

The  Corbin  Cylinder 
Showing  Key-way 


Fig.  93 

The  Corbin  Cylinder 
Without  Master  Key 


Fig.  94 

The  Corbin  Cylinder 
With  Master  Key 


The  Corbin  ball-bearing  pin  tumbler  locking  cylinder  is  the  highest  development  of  key  operated 
mechanism.  It  has  all  the  advantages  to  be  given  by  any  other  cylinder  and  a  number  not  to  be  obtained 
elsewhere,  and  can  be  used  where  any  other  cylinders  are  employed. 

The  key-way  has  projections  on  both  sides  which  reach  the  center,  making  it  impossible  to  insert  a 
flat  picking  tool  or  to  use  any  other  than  a  Corbin  key  of  the  proper  class. 

The  key  plug  is  turned  by  the  key  and  carries  the  lever  which  throws  the  bolt.  It  is  cut  from  a  solid 
cylindrical  bar,  and  the  key-way  is  cut  into  it  by  special  machinery  of  great  accuracy.  It  is  released  by  the 
service  key. 

The  master  ring  is  a  Corbin  invention  and  is  found  alone  in  Corbin  cylinders.  It  provides  a  new  point 
for  the  release  of  the  key  plug  and  in  effect  gives  two  locks  in  a  single  case,  each  perfectly  independent  of  the  other, 
so  far  as  key  changes  are  concerned.  The  master  key  releases  the  key  plug  and  the  master  ring,  which  rotate 
together.  It  is  thus  possible  to  have  the  service  keys  of  a  number  of  locks  all  different  but  to  have  the 
cylinders  so  made  that  the  same  master  key  will  unlock  them  all.  The  convenience  and  reliability  of  the 
Corbin  master-keyed  cylinder  as  compared  with  two  cylinders  or  one  cylinder  with  two  key-ways  is  apparent. 

The  pins  serve  as  bolts  and  hold  the  rotating  key  plug,  or  key  plug  and  master  ring,  firmly  in  place  until 
the  insertion  of  the  proper  key  raises  them  to  a  position  which  releases  the  plug.  A  variation  of  a  thousandth 
of  an  inch  from  correctness  will  make  the  key  inoperative.  The  number  of  pins  and  the  number  of  possible 
points  of  separation  on  each  pin  make  the  number  of  key  changes  practically  unlimited  and  give  a  great 
degree  of  security. 

The  shell  is  a  bronze  casting,  into  which  the  other  parts  are  fitted.  In  use,  the  body  of  the  cylinder  is 
concealed,  the  only  visible  portion  being  the  end  or  face,  the  mechanism  being  only  approachable  from  the 
front. 

The  lever  or  trip  at  the  end  of  the  key  plug  is  varied  to  suit  the  nature  of  the  work  to  be  done,  the  line 
of  Corbin  door  locks  embracing  every  function  and  type  required  by  modern  conditions.

HARDWARE  OF  SPECIAL  DESIGNS 


Fig.  96 

The  Corbin  designers  make  a  specialty  of  artistic  interpretation  of  architects’  sketches. 
They  are  familiar  with  the  treatment  of  the  detail  of  ornament  in  the  different  periods  of 
art  and  faithfully  reproduce  the  characteristics  of  each.  When  desired,  sketches  in  harmony 
with  the  architects’  motifs  will  be  submitted.
